Enhanced P&O Technique for Multi Stage Grid Interfaced Solar Cell

Abstract

This paper presents an adaptive perturbation and observation algorithm for Maximum power point tracking of solar photo voltaic cell. The solar cell interfaced with grid network in double stage mode using 3-phase converter. The 3-phase converter is used to reduce the harmonics in the system. It is used voltage source inverter to maintain the power quality norms with fewer harmonic as per IEEE-519 standard. The Matlab Simulink is used for simulation. The algorithm performance is observed in different environmental condition using experiment prototype in the laboratory. The PV cell obey different characteristics at different environmental conditions. The P&O algorithm is adopting by many industries due to its simplicity.
